I wanted to try this medallion-style tangle on a 3Z tile for a while now. I like the way it turned out, even though shading was a bit of a challenge. I ended up using some black colored pencil in the background areas to increase the contrast. I think that created a a very interesting look.
For even more contrast, I added a bit of white, charcoal pencil to create some highlights.
I love the end result!
